DFS is a very generic term for a system that makes files available from multiple physical locations. This can be redundant copies (for performance or redundancy); or it can be a single logical file system with individual files placed on different physical servers.

Distributed Storage is abstracting the physical storage through a single logical presentation; basically you have storage in multiple locations (different servers or dedicated hardware), which looks to the application as though it's a single storage system.

To an extent, they're being used as marketing buzz-words. They will mean nothing unless you know exactly how they're implemented, and thus how to take advantage of them.
